I-IAMILTON F. LOW, OF CLEVELAND, OHIO, ASSIGNOR TO LOUIS KOEHL, OF SAMEPLACE.

MOP-HEAD SPECIFICATION forming part of Letters Patent No. 519,917, datedMay 15, 1894. Application led May 27, 1893. Serial No. l175,687. (Nomodel.)

To a/ZZ whom t may concern,.-

I Se it known that I, HAMILTON F. Low, a

cltizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of 5 Ohio, have invented certain new and usefulImprovements in Mop-Heads; and I do hereby declare the following to be afull, clear,

and exact description of the invention, such as will enable othersskilled in the art to which Io 1t appertains to make and use the same.

y This invention relates to certain improvements in mop-heads; theobject being to pro duce a mop`-head of novel construction which shallbe light, strong and cheap.

The invention consists in the construction and combination of partsshown in the drawings and hereinafter described and pointed out in theclaims.

In the drawings, Figure l is a front elevazo tion of my improvedmop-head. Fig. 2 is a central sectional view of the base and partsadjacent thereto; and Fig. 3 is a side view of a part of the base andthe means for connecting the frame thereto.

The base A of the mop-head is tubular, whereby the handle may beinserted at one 4 end and the stem of the follower may enter the other,The frame B is made of wire so bent that it forms two parallel sides l)b which 3o guide the follower; a connecting cross bar b between whichand the follower the mop is held; and the converging ends b2 b2 whichare connected with the base. As the means for connecting these ends withthe base I con struct the base preferably of malleable iron,

and form on each side thereof two lugs d a. Each end of the frarneisplaced between two of these lugs which are then upset or bent down ontosaid ends.` This prevents the dis 4o connection of said ends by movementin a sidewise direction. `To prevent their disconnection by moving themlongitudinally, I also form on the base the iianges a. a which engagewith the parts of the ends b2 b2 which diverge from said base, as shownmost clearly in Fig. 2. The follower C is made of wire bent intosubstantially the forni shown. The cross bar c of said follower is madeof two strands of wire twisted together to stiffen them. This part ofthe follower should be 5o substantially parallel to the part b of theframe, and it is so held and guided in its movement by the loops c',formed by bending the wire backward toward the center and the sides b bwhich pass through said loops. At substantially the center of thefollower one end c2 of the wire of which it is formed is bent at rightangles to the part c, and forms a stem. v The other end c3 of the wireis wound Spirally about said stem thereby forming a 6o spiral rib orthread with which the thumb nut D engages. The thumb nut on its underside has two notched ears d d which embrace an annular flange a2 on thebase, thereby preventing longitudinal motion of the nut but permittingit to be revolved. The nut has a spirally grooved central hole withwhich it engages with the threaded stem of the follower; and it also hasside wings d d by means of which it may be revolved.

Having described my invention, I claiml. In a mop-head, the combinationof a frame having a transverse cross-bar, two parallel sides andconverging ends, a base to which said ends are secured, and an annularilange a2 on said base, with a follower having a rigidly connectedthreaded stem, and a. nut which engages with said stem and two notchedears secured to said nut which embrace the flange a2, substantially asset forth.

2. In a mop-head, the combination of a base having the annular iiangea2, and a frame consisting of a transverse cross-bar, two sides and twoends which are secured to said base, with a follower -having loops atthe ends of its cross-bar and a stem formed of one straight wire and onewire wound spirally about the straightwire, and a nut which engages withsaid stem and has two notched ears which engage with the ilange 0.2,substantially as 9o set forth.

In testimony whereoflafx my signature in presence of two witnesses.

HAMILTON F. LOW.
